* util/grub-pe2elf.c: New file.
* configure.ac: Set TARGET_OBJ2ELF if host os is cygwin. Don't test for
start symbol in non pc platform.
* genmk.rb: Use TARGET_OBJ2ELF to convert native object format to elf.
The following patches are from Christian Franke.
* include/grub/dl.h: Remove .previous, gas supports this only
for ELF format.
* include/grub/symbol.h [__CYGWIN__] (#define FUNCTION/VARIABLE):
Remove .type, gas supports this only for ELF format.
* kern/dl.c (grub_dl_resolve_dependencies): Add check for trailing
nullbytes in symbol table. This fixes an infinite loop if table is
zero filled.
* Makefile.in: Add autoconf replacements TARGET_IMG_LDSCRIPT,
TARGET_IMG_LDFLAGS and EXEEXT.
* aclocal.m4 (grub_PROG_OBJCOPY_ABSOLUTE): Replace -Wl,-N by
TARGET_IMG_LDFLAGS_AC.
(grub_CHECK_STACK_ARG_PROBE): New function.
* conf/i386-pc.rmk: Replace -Wl,-N by TARGET_IMG_LDFLAGS.
* conf/i386-pc-cygwin-ld-img.sc: New linker script.
* configure.ac: Add check for linker script "conf/${target}-img-ld.c"
to set TARGET_IMG_LD* accordingly.
Add check for Cygwin to set TARGET_MOD_OBJCOPY accordingly.
Add call to grub_CHECK_STACK_ARG_PROBE.
Use TARGET_IMG_LDFLAGS to check start, bss_start, end symbols.
* genkernsyms.sh.in: Handle HAVE_ASM_USCORE case.
* genmk.rb: Add EXEEXT to CLEANFILES.
* kern/i386/linuxbios/init.c (grub_machine_init): Cast addr to
grub_addr_t before casting it to the void pointer to fix a
warning. Non-addressable regions are discarded earlier.
(grub_arch_modules_addr): Cast _end to grub_addr_t.
* kern/i386/linuxbios/table.c: Include grub/misc.h.
(check_signature): Don't shadow table_header.
(grub_linuxbios_table_iterate): Cast numeric constants to
grub_linuxbios_table_header_t.
* include/grub/i386/linuxbios/init.h: Add noreturn attribute to
grub_stop().
